I printed $avgSQL and got:

It looks OK to me, but then again, I'm a novice at SQL.
I do a lot of preprocessing to the csv files before I run them through the perl script. I remove spaces, , , (, ), etc... the list above has all column names in it. I'm wondering if this should be looped? These csv files will average about 30 columns and upto 6000 rows. Doing all the average calculations in one command may be a little taxing on my system.

PS. I don't need the data after the average is calculated. Just the column name and the average. Also, I don't need the first column, that can just go away.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.


Come for the quick hacks, stay for the epiphanies.
